SASH-LOCK.

Specification of Letters Patent. Patented Nov, 16, 1915.

Application filed June 15, 1915. Serial No. 34,156.

T allwkom it may concern:

Be it known that I, WILLIAM J. Wear, a citizen of the United States,residing at Clay City, in the county of Pierce and State of W'ashington,have invented certain new and useful Improvements in Sash-Locks, ofwhich the following is a specification, reference being had to theaccompanying drawings.

The present invention relates to new and,

useful improvements in sash locks for windows and, as its principalobject, aims to provide an improved device of this character which isrelatively simple in construction and may, therefore, be cheaply manufactured, and is of such design that it may be easily and quicklyapplied to or removed from any window casing of standard design withoutrequiring any alterations or changes in the construction of either thecasing or the sashes and without necessitating the application ofpermanent fastening devices to either the casing or sashes.

A further and more specific object of the invention is to provide a sashlock of the character above stated which consists generally in twohi-ngedly united sections, one of which constitutes the attaching plateand is accompanied by spurs adapted to be embedded in the sash bar orwindow casing for holding the device against movement, and the other ofwhich is formed in the nature of a wedge-shaped locking block which isdesigned to be inserted between the two sashes for preventing movementof the two sashes relative to each other.

, The above and other incidental objects of a similar nature, which willbe hereinafter more specifically treated, are accomplished by such meansas are illustrated in the accompanying drawings, described in thefollowing specification, and then more particularly pointed out in theclaims which are appended hereto and form a part of this application.

With reference to the drawings, wherein there has been illustrated thepreferred embodiment of the invention as it is reduced to practice andthroughout the several views of which similar reference numeralsdesignate corresponding parts, Figurel is a perspective viewillustrating two possible applications of the sash lock to a windowsash; and Fig. 2 is a detail perspective view of the sash lock.

The structural details of the preferred form of the sash lock areillustrated in deta l 1n Fig. 2 and, for this reason, reference willfirst be had to this figure. As there shown, the lock consists generallyin an at tachlng or body plate and a wedge block 11. The two members 10and 11 are hingedly united by means of a hinge 12 which may be formedeither as an integral part of the plate and block or may be designed asa separate element and suitably secured thereto in any desired manner.The plate and block are both preferablyv formed as metallic castingsalthough, may alone be made of metal and the block formed of wood orsome light but tough composition.

if desired, the plate The attaching or body plate 10 is preferarerelatively sharp and adapted to be em- I bedded in either the windowcasing or the window sashes, as will be hereinafter more particularlypointed out, for holding the locking device in the proper position andagainst movement. These studs or spurs are, of course, relatively shortsince it is not intended that the present device shall, when applied tothe window casing or window sashes, deface these members.

The actual construction and arrangement of the several parts of the lockdevice being thus disclosed, reference will now be had to Fig. 1 andparticularly to the right hand side thereof, wherein the device is shownas attached to the window casing. As disclosed, the attaching or bodyplate is applied to the vertical face board 14 of the window casing andis disposed in the vertical line which separates the upper and lowersashes.

venting the lower sash from being opened.

In some instances, it may be desirable to As previously stated, the bodyplate is held 1n proper position and against movement so apply thelocking device that it will hold both the upper and lower sashes frommovement. Such application of the device is illustrated at the left, inFig. 1. As therein shown, the spurs of the plate 10 are forced into thevertical bar 18 of the'upper sash and the lower end of the wedge blockinserted between the meeting rails 16 and 17 of the upper and lowersashes respectively. It will, of course, be understood that the wedge isfirst placed in position, 'at which time the plate 10 is turned downinto angular relation to the wedge and then after the wedge 11 has beeninserted between the meeting rails, the plate 10 is turned back againstthe vertical rail 18 of the window sash and the spurs I?) forced intothe wood of the rail or bar. The hinge connection between the plate 10and the wedge 11, permits the plate 10 to be forced rearward, even wheremeeting rails are of different widths. Furthermore, in detaching thedevice, it is only necessary to pull outward on the plate 10, thusreleasing the prongs 13 from the vertical bar, whereupon the wedge maybe readily withdrawn, the plate, in that case, acting as a.

handle. It will be obvious that when the device is in place, as shown inFig. 1, it cannot be readily disengaged by the insertion of aninstrument between the meeting rails of the sashes, as the hinge 12 willprevent any rotation'of the Wedge in the plane of the plate 10.

In concluding the description of the invention, I now desire to directparticular attention to the practical utility of my window lock.Obviously, the lock may be carried' by travelers and transients, andsince it is composed of two hingedly united sections, will occupy aminimum space when in transit. In case the owner of the sash lock islodging in a strange hostelry, he may guard himself against intrusion byapplying the sash lock to the window. My sash lock is particularlyemployed for such' purposes since it may be so quickly and easilyapplied to-or removed from the window sashes.

Having thus fully described my invention,

what I desire to claim and secure by Letters Patent is 1. A sash lockadapted for temporary application to window sashes comprising anattaching plate having means whereby it may be secured in place, and anormally depending wedge block hingedly attached to the lower edge ofthe plate for movement in a plane at right angles to the face of theplate and the upper edge of the plate and from a depending positionapproximately depending position into angular relation to the face ofthe plate.

3. A sash lock adapted for temporary application to window sashescomprising an attaching plate having spurs upon its rear face adaptedto. be temporarily embedded in the woodwork of a window, a hinge leafhingedly connected to the lower end of the plate and movable in a planeat right angles to the face of the plate and to the lower edge of theplate, and a wedge block, t9 the butt end of which said hinge leaf '1attached whereby the block is movable in a plane at right angles to theface of the plate.

In testimony whereof I hereunto afiix my signature in the presence'oftwo witnesses.
